Description

The invention relates to a set of a connector and a holding element, wherein the connector has a Isolierstoffgehäuse and the connector and the holding element are designed for locking with each other. The retaining element has latching elements projecting from a bearing surface of the retaining element.

The invention further relates to a connector and a retaining element for this purpose.

DE 203 18 084 U1 discloses a strain relief device for the connection lines of a connector in the form of a cable holder, which can be plugged into corresponding receptacles of a connector and optionally latched there.

DE 10 2010 010 259 B1 discloses a connector with an insulating housing and with a separate strain relief. The strain relief element has at its free end projecting locking elements, which dive into associated grooves of the connection side of the connector and lock behind a cross bar with the connector. For this purpose protrude locking projections of the locking elements in the groove behind the crossbar of the connector and together with the crossbar form a handshake, which prevents removal of the strain relief from the connector.

Proceeding from this, it is an object of the present invention to provide an improved set of connector and retaining element and a corresponding connector and an associated retaining element.

The object is achieved by the set with the features of claim 1 and with the connector with the features of claim 14 and the retaining element having the features of claim 23. Advantageous embodiments are described in the subclaims.

It is proposed that the connector on a Anrastfläche has a plurality of detent openings, which have a Einsteckbereich for receiving in each case one in a perpendicular to the Anrastfläche aligned immersion direction in the insertion region inserted locking element and an adjacent detent region. The latching region has a latching edge for positive latching of a latching element of the holding element and on the Anrastfläche a smaller opening than the Einsteckbereich to lock according to a transversely to the dipping direction relative transverse displacement of the holding element and connector to each other inserted into the plug-in locking element in the latching area with the locking edge ,

Thus, the support member is placed in a vertical movement perpendicular to the Anrastfläche with its bearing surface on the Anrastfläche so that the locking elements in the sufficiently wide open insertion region of the associated detent openings dive. Then takes place in a position in which the holding element rests on the connector, a transverse displacement to move the locking elements from the insertion in the adjacent latching area and there to lock each at an associated locking edge. In this way, at least one positive stop for the locking elements is formed, with which the retaining element is secured to the connector.

The detent opening is an opening or depression in the insulating housing of the connector on the Anrastfläche, which is divided into two merging areas, the insertion and the catch area, both of which open at the common Anrastfläche.

Such a set is very compact and simple and provides a reliable connection of the holding element to the connector ready. The handling for mounting is very easy in two steps by attaching the retaining element on the connector for inserting the locking elements in the locking openings and then lateral displacement of the retaining element relative to the connector possible.

For the purposes of the present invention, the indefinite term "a" is to be understood as such and not as a number word. Thus, additional elements are not excluded, such as a multi-part.

The insulator housing of the connector may have juxtaposed conductor insertion openings extending in a conductor insertion direction into the insulator housing to conductor terminals in the insulator housing. The Anrastfläche of the connector may be the surface of the connector, in which the latching openings are introduced and which is parallel to the plane which is spanned by the arrangement direction of the juxtaposed conductor insertion openings and by the Leiterereinsteckrichtung, or parallel to a plugging direction of the connector. Thus, the support plate is aligned parallel to the plane of a bundle of electrical conductors which are plugged into the connector. In this way, the latching of the retaining element is adapted to the connector to the force of the clamped electrical conductors.

The insertion region and the latching region of a latching opening of the connector can lie next to one another in the direction of arrangement of the conductor connection terminals. Thus, for latching of the holding element to the connector, a transverse displacement of the holding element in a direction transverse to the extension direction of the clamped electrical conductors. If the holding element is used as a strain relief element, then a force is exerted by a tensile force of the electrical conductor to the strain relief element, which is transverse to the locking direction of the holding element on the connector. Thus, the secure locking of the retaining element is not affected on the connector.

A first group of latch openings of the connector may be arranged side by side in a first row. Furthermore, at least one second detent opening can be arranged at a distance from this first row. The latching openings of the first group in the first row then act together with the at least one further latching opening which lies outside the first row, so that a tilt-proof latching is achieved.

It is conceivable that a second group of latching openings in a second row is arranged side by side, wherein the second row is spaced from the first row. There may also be more than two rows of groups of detent openings, such as three or four rows. Thus, the lock can be distributed on the Anrastfläche and the power flow can be made uniform.

It is conceivable that the at least one second latching opening are arranged offset to the latching openings of the first group with respect to the plugging direction and / or the conductor plugging direction. Such an offset of the latching openings arranged in the adjacent rows counteracts excessive weakening of the material of the insulating material and improves the flow of force in the locking of the retaining element on the plug connector.

The latching elements of the holding element can be designed as a latching hook with a holding arm extending away from a base surface of the holding element and a latching projection projecting from the holding arm. Such a latching hook can then dip with its locking projection in the correspondingly large opening of the insertion. In the transverse displacement of the latching hook in the latching area then a positive connection between the latching projection and the latching edge of the latching area is formed. For this purpose, the latching projection is pushed under the latching edge. The latching hook can in this case e.g. have an L-shaped contour.

The latching projection of a first group of latching elements can point in a first direction. The latching projection of at least one further latching element can then point in a direction opposite to the first direction. Thus, at least two facing in opposite directions latching hooks form a complementary pair of locking elements which act in the opposite direction or improve the locking of the retaining element to the connector.

The connector can be multi-part. The holding element can then be designed for the positive connection of the plurality of insulating material of the connector. Thus, the latchable on the connector holding element can be used to connect the insulating material together and prevent falling apart of the insulating material. The retaining element thus forms a clip connecting the Isolierstoffgehäuseteile.

However, the retaining element can also be designed to connect two plugged connectors to prevent unintentional removal of the connectors from each other. For this purpose, a set of first and second connector has a latchable with these two connectors holding element.

The retaining element may be a strain relief element with a projecting platform of the connector with fastening contours for fastening an electrical line. The plugged into the connector electrical conductors can be secured, for example. With cable ties to the platform of the holding element. If a tensile force is exerted on the electrical conductors, this is intercepted by the holding element and transferred via the latching connection of the holding element with the connector on this total.

The connector and the retaining element may have securing structures which prevent or complicate a transverse displacement of the retaining element for movement of the locking elements of the retaining element from the latching region of the locking openings of the connector out into the insertion by positive engagement or frictional engagement. In order for a further locking of the retaining element is provided on the connector on the latching with the dipping into the locking openings locking elements addition. Such securing contours can be formed from at least one pair of locking nubs and an associated locking recess. In the latched state, in which the latching elements are locked in the latching areas of the latching openings, such a locking knob plunges into an associated latching recess and prevents a transverse shift back to the unlocked state. For this purpose, then such a large force would have to be spent, which allows the sliding out of the locking knob from the locking recess out.

The width of the detent openings can be adapted to a whole pitch. The insertion area and the latching area are then each adapted to a half pitch. An entire pitch corresponds to the distance of adjacent conductor insertion openings from each other. This is used according to the pitch width of the connector for each Leitereinstecköffnung a customized latching opening. The retaining element must be transversely displaced by only half a pitch width after placement on the connector. The width of the latching openings can here correspond to half the pitch. But it can also be a bit narrower, e.g. 90% of the pitch width, so as not to unduly weaken the insulator housing.

The width of the detent openings can also be adapted to half a pitch. The insertion area and the rest area are then each adapted to a quarter pitch. Other widths of the latching openings and other width ratios between plug-in area and latching area are conceivable. However, if possible, the width of the insertion region and the latching region should each be half the width of the latching opening.

The retaining element only has to be displaced by a relatively small distance, which is smaller than a pitch.

The formation of the latching opening with a half pitch width for the insertion area and a half pitch width for the latching area has a very even force application over the entire width of the connector in a double row arrangement of groups of detent openings, which are arranged alternately offset from one another.

A corresponding solution, in which the introduction of force is even more uniform, provides the division of the detent openings with a width of one quarter pitch for the insertion and a quarter pitch for the detent region with four rows, the detent openings are arranged alternately offset from one another.

The latching openings of the connector provide the ability to accommodate different types of support elements, such as. Mounting adapter, locking elements, locking feet, shielding plates, etc.

A continuous receiving groove is avoided by the detent openings, so that the air and creepage distances are not reduced too much on the latching surface of the connector.

For the purposes of the present invention, the indefinite term "a" is to be understood as such and not as a number word. Thus, additional elements and a multi-parting are not excluded, even if this fact in the individual case by "at least one" is particularly highlighted.

1 shows a perspective view of a set of a connector 1 and a holding element 2 , The holding element 2 is designed as a strain relief and has one of the connector 1 protruding platform 3 with fastening contours 4 in the form of openings and indentations, with which, for example, cable ties on the platform 3 can be connected. This makes it possible electrical conductors (not shown), in the connector 1 be plugged in at the platform 3 to fix.

The connector 1 has an insulating material housing 5 , This is executed in several parts in the illustrated embodiment and consists of several Isolierstoffgehäuseteilen that are stuck together. At the Leiterereinsteckseite has the connector 1 a plurality of conductor insertion openings arranged side by side in a row 6 leading to conductor terminals in the interior of the insulating material 5 lead to the ladder insertion holes 6 introduced electrical conductors to the connector 1 anzuklemmen. Opposite to the conductor insertion side is a plug contour 7 of the insulating material housing 5 provided with plug contacts arranged therein.

Recognizable are also operating openings 8th on the Leiterereinsteckseite above the respective Leiterereinstecköffnungen 6 , These each lead to a conductor terminal and are provided and adapted to by insertion of an actuating tool a spring force terminal connection in the interior of the connector 1 to open.

It becomes clear that the retaining element 2 at the bottom of the connector 1 is superimposed. This underside of the connector 1 forms the locking surface of the connector 1 , There are detent openings 10a . 10b present, in the locking elements 11 of the holding element 2 dive to the retaining element 2 on the connector 1 to lock.

The locking elements 11 of the holding element 2 are designed as latching hooks with an L-shaped contour.

2a) shows a perspective view of the connector 1 out 1 overlooking the Anrastfläche 9 , There are three detent openings in two rows 10a . 10b arranged side by side. The detent openings 10a . 10b have a plug-in area 12 and an adjacent rest area 13 , The rest area 13 goes into the plug-in area 12 over, so that there is a continuous connection. The at the Anrastfläche 9 Ausmündende opening cross-section of the locking area 13 is smaller than the one at the catching surface 9 opening opening cross section of the insertion area 12 , This is due to the fact that a locking edge 14 in the form of a bridge in the detent opening 10a . 10b in the area of the rest area 13 protrudes. This locking edge 14 forms a stop for the locking element 11 of the holding element 2 ,

It can be seen that the outer detent opening 10b the second row of detent openings 10a that is closer to the mating side than to the conductor insertion side, to the latching area 13 is reduced. The insertion area 12 is not required there, as the locking element 11 initially next to the sidewall of the connector 1 can be positioned to then enter the rest area 13 to be pushed in.

2 B) shows the connector 1 out 2a) facing the other side. There it becomes clear that the locking edge 14 in the detent opening 10a . 10b protrudes, wherein below the web-like locking edge 14 a free space remains.

It is also recognizable that the insertion area 12 the latch opening 10a . 10b the same length (ie transverse displacement) as the detent area 13 , but one in the size of the locking edge 14 has greater width. Thus, the cross section of the outlet in the insertion area 12 greater than in the rest area 13 ,

It is clear that the width of a detent opening 10a . 10b a division width corresponds approximately. An entire division width is the distance of the center axes of two adjacent ones Conductor insertion openings 6 from each other. The width of the insertion area 12 and the rest area 13 each corresponds to about half the pitch width.

It is also recognizable that between the detent openings 10a . 10b two adjacent poles of the connector 1 , with each pole of a connector 1 a conductor insertion opening 6 is assigned for insertion of an electrical conductor, not shown, in each case a web 18 remains, which you Rast openings 10a . 10b adjacent pole separated from each other. The jetty 18 closes with the locking surface 9 flush and provides a sufficient clearance and creepage distance between the poles associated Isolierstoffgehäuseteile the connector 1 for sure.

The latching openings arranged in the two rows 10a . 10b are alternately offset from each other, so in Leitereinsteckrichtung L eg. A plug-in 12 a detent opening 10a the first row a rest area 13 an underlying detent opening 10b the second row follows. Accordingly, the detent openings 10a the first row closer to the conductor entry openings 6 is located, transversely offset by half a pitch width to the underlying detent openings 10b the second row, the closer to the plug connections 7 lies.

3a) shows a perspective view of the retaining element 2 in the form of a strain relief 1 , It becomes clear that the retaining element 2 is plate-shaped and a platform 3 with the formed as openings and side incisions or hollows fastening contours at the free end. The holding element 2 has a support surface 15 from which the locking elements 11 in a common direction. The locking elements 11 are as latching hooks with one integral with the support surface 15 shaped hook arm 16 and a transversely projecting locking projection 17 educated.

It is also recognizable that the locking elements 11 arranged in groups in two rows. The locking elements 11 a group are lined up in an alignment with a distance next to each other. The rows are transverse to the longitudinal direction of the holding element 2 aligned and in the longitudinal direction of the holding element 2 spaced apart and arranged parallel to each other or aligned.

It is also clear that the locking elements 11 the first group in the first row with their locking projection 17 in one direction from the locking elements 11 The second row protrude away direction. The same applies to the locking projections 17 the locking elements 11 the second group. The locking projections 17 the first group of locking elements 11 thus have in a first direction and the locking projections 17 the locking elements 11 the second group in a direction opposite to the first direction. In this case, the locking lugs 17 away from each other in this embodiment. Alternatively, however, they can also be oriented toward each other.

It is also recognizable that the locking elements 11 are alternately offset from one another from the first row to the second row. The locking elements 11 The second row are thus in the alignment transverse to the direction of arrangement of the respective group seen in the space between the locking elements 11 the other group.

3b) shows a holding element 2 that no platform 3 has and only as a connecting element for connecting a multi-part connector 1 is provided. Here it is once again clear that the groups arranged in each case in a row locking elements 11 alternately offset from a first row to the second row and vice versa. The holding element 2 according to the 3b) can be provided for attachment to a surface of a printed circuit board or other substrate, for example by gluing or not shown by other fasteners, for example. Detent means, on the surface with the locking elements 11 remote surface. Furthermore, it is conceivable that the holding element 2 on the surface with the locking elements 11 facing away from a locking contour for latching on a mounting rail.

It is also clear that the locking elements 11 as an L-shaped locking hook with one of the support surface 15 protruding hook arm 16 and one each transverse to the free end of the hook arm 16 protruding locking projection 17 are formed. Below the locking projection 17 is a free space available in the web-like locking edge 14 the latch opening 10a . 10b of the connector 1 is positioned when the connector on the retaining element 2 put on and moved across. With the retaining lip 17 and the associated locking edge 14 of the connector 1 a positive connection is provided.

It is also clear that the hook arms 16 integral with the retaining element 2 For example, are formed of plastic material. They can be conical to the retaining lip 17 or to run towards their free end, so a more stable connection to the support surface 15 provide.

As an alternative to the L-shaped outline of the latching hook designed as latching elements, these could also be a T-shaped or Dovetail-shaped contour, in which case the contour of the detent openings 10a . 10b is adjusted accordingly.

Unless the formation of the holding element 2 as strain relief according to the 3a) is provided with a metallized surface or coating, the retaining element 2 also be used as a shielding element.

4a) shows a perspective view of a set of connectors 1 and the holding element 2 out 3b) in the pre-lock position. It becomes clear that the retaining element 2 on the left in the direction of view from the contour of the connector 1 survives and the connector 1 on the right side with its contour the holding element 2 survives. A locking element 11 of the holding element 2 is next to the connector 1 positioned. In this area is the detent opening 10a . 10b of the connector 1 laterally open, so that the locking element 11 at a transverse displacement of the connector 1 to the left or a transverse displacement of the retaining element 2 to the right in this latching opening 10a . 10b hineingleitet and in the latching area located there 13 is locked by positive locking.

In 4b) is the perspective view of the set 4a) to recognize in the locked position. It becomes clear that now the connector 1 and the holding element 2 are shifted relative to each other across the conductor insertion direction L, so that their contours no longer survive against each other. Here is the locking element 11 of the holding element 2 in the detent opening 10a . 10b pushed in, so that the locking projection 17 the locking element 11 together with the locking edge 14 of the connector 1 or the latching opening 10a . 10b form a stop to each other. In this way, the retaining element 2 positive fit on the connector 1 locked.

5 shows a side view of the set 4a) and 4b) with the section line EE in the region of the support surface 15 of the holding element 2 and the adjacent Anrastfläche 9 of the connector 1 , Visible is that of the bearing surface 15 of the holding element 2 an average L-shaped locking element 11 protrudes from the tapered hook arm 16 and the locking projection projecting transversely thereof 17 is formed. It becomes clear that the locking element 11 in the detent opening 10a . 10b of the connector 1 dips into the snapping area 9 is introduced. In the illustrated section is the locking element 11 in the latching area of the latching opening 10 , so that the web-like locking edge 14 which the detent opening 10a . 10b limited in the locking area, the locking projection 17 engages and between the locking projection 17 and the bearing surface 15 is positioned. Incidentally, the locking element 11 also positively in the locking opening 10a . 10b so that the range of motion between connectors 1 and holding element 2 is restricted. It is also conceivable a recording of the locking element 11 in the latch opening 10a . 10b in the latching area with a press fit, so that over the form fit also a traction or at least one frictional connection is provided.

6a) shows the sketch of the set of connectors 1 and holding element 2 out 4a) in the pre-locking position in the section EE. Here are the locking elements 11 recognizable in the plug-in area 12 one from the plug-in area 12 and the adjacent rest area 13 formed latching opening 10a . 10b are plugged in. The opening in the insertion area 12 , ie the cross section of the outlet from the Anrastfläche 9 , is at least as large as that of the hook arm 16 and the protruding locking projection 17 spanned perpendicular to the support surface 15 of the holding element 2 projected area. It can be seen that the retaining element 2 in the pre-locked position offset to the contour of the connector 1 on the insulating material 5 is plugged. In this case, the holding element 2 with its support surface 15 perpendicular to the locking surface 9 of the connector 1 put on so that the locking elements 11 in associated detent openings 10a . 10b plunge.

Then there is a transverse displacement of the retaining element 2 at the level of the overlapping locking surface 9 and bearing surface 15 transverse to the conductor insertion direction L.

It becomes clear 6b) in that the locking elements 11 now from the plug-in area 12 across the adjacent resting area 13 are moved in. This overlaps the web-like locking edge 14 that are at the level of the catching surface 9 of the connector 1 in the respective detent opening 10a . 10b protrudes, the locking projection 17 the inserted therein locking element 11 , The opening cross section of the locking area 13 is compared to the opening cross section of the insertion area 12 smaller and corresponds approximately to the cross-sectional area of the hook arm 16 in its height, when the locking element 11 in the detent opening 10a . 10b is plugged in.

7 shows a plan view of the connector 1 on the left side overlooking the catching area 9 and on the right with a view of the snapping area 9 opposite top of the connector 1 , The section lines AA and BB are shown.

It can be seen that the detent openings 10a . 10b arranged in groups in two rows next to each other. These two rows are each aligned transversely to the conductor insertion direction L. In this direction across the conductor insertion direction L is next to a plug-in area 12 the detent openings 10a . 10b a rest area 13 with a smaller opening cross-section available.

It also becomes clear that the detent openings 10a . 10b are alternately offset, so seen in Leiterereinsteckrichtung L in the escape behind a plug-in 12 a first detent opening 10a . 10b a rest area 13 follows and vice versa. The at the positive connection to the insulating material 1 transmitted forces are thus on the Anrastfläche 9 at least largely evenly distributed.

8a) shows a partial cross-sectional view of the connector 1 on average AA. It becomes clear that the detent openings 10a . 10b on a cutting plane, for example in section AA, on the one hand a plug-in area 12 the latch opening 10a . 10b and in Leitereinsteckrichtung following a plug-in area 12 with one in the detent opening 10a . 10b protruding ridge-like locking edge 14 to have. This is a plug-in area 12 and rest area 13 alternately staggered.

In 8b) is the partial cross-sectional view of the connector 1 shown in section BB. There is now the rest area 13 with its locking edge 14 on the left and the plug-in area 12 On the right side. insertion 12 and rest area 13 are thus alternately offset from each other in Leitereinsteckrichtung L and arranged transversely thereto.

9a) shows a partial cross-sectional view of the set of connectors 1 and holding element 2 on average AA. There it can be seen that the cut left locking element 11 of the holding element 2 in the latching area of a latching opening 10a . 10b located.

Also the right locking element 11 , Due to its offset transversely to the Leiterereinsteckrichtung, ie in the direction also in a staggered latching area 13 dips. Also this locking element 11 will be in the rest area 13 through a locking edge 14 locked.

9b) shows the partial cross-sectional view of the set of connectors 1 and holding element 2 in section BB. Here is the section through the right locking element 11 , which is located in the rest area 13 located and through the locking edge 14 is locked.

Also the not cut locking element 11 , which is offset in the direction of view, is located in a rest area 13 and also by the locking edge 14 locked, which is now completely visible in the view on the front page. The cutting plane BB runs on the left side through the insertion area, which is not through the locking edge 14 is limited, and on the right by the through the locking edge 14 limited rest area 13 ,

10a) shows a perspective view of a set of two mated connectors 1 , These are with their plug connections 7 put on each other and contact each other.

The holding element 2 is intended to prevent unintentional removal of the two connectors 1 prevent each other. For this purpose, the connectors 1 with the help of the retaining element 2 locked together.
